Hashi integrates multiple oracles to relay block headers and messages securely across different blockchains. Each oracle operates with its own set of contracts and mechanisms depending on the source and destination chains. Below are the deployment details for each oracle, including testnets when available.
A GMP Oracle (General Message Passing Oracle) facilitates message transmission across different blockchain networks by acting as a trusted entity to validate, relay, and process cross-chain messages, ensuring that data or instructions are accurately transferred between chains.
is a cross-chain communication protocol. It allows developers to configure security through Decentralized Verifier Networks (DVNs), offering modular control over message validation. LayerZero currently supports 49+ chains.

Gnosis Chain's Arbitrary Message Bridge (AMB) is the chain's legacy canonical bridge. It enables cross-chain communication between Gnosis Chain and Ethereum (and other EVM networks). It allows contracts to send data and trigger actions on another chain through a set of decentralized validators.

A ZK Light Client is a lightweight blockchain client that uses zero-knowledge proofs (ZKPs) to securely verify and relay blockchain state data between networks.
Light client-based oracles don't need for a reporter contract on the source chain to dispatch messages or block headers. Instead, they only require an adapter on the destination chain. Off-chain systems generate cryptographic proofs, which are submitted to the adapter contract for on-chain verification. Once validated, the resulting hash is securely stored on the destination chain.

is a crypto-economic coprocessor that enables secure and efficient cross-chain interoperability by offchain proof verification and decentralized relayer communication.
is a cross-chain interoperability protocol that connects over 30 blockchains. It uses a decentralized network of 19 Guardians to validate cross-chain messages through a mechanism called Verifiable Action Approvals (VAAs).
facilitates secure token transfers and cross-chain messaging across nine blockchains. It integrates decentralized oracle networks and a Risk Management Network to ensure security for cross-chain applications.
is a ZK light-client-based oracle focusing on updating and verifying block headers without needing a reporter on the source chain. It ensures enhanced security by allowing proofs to be generated off-chain and verified on-chain.
is a ZK light-client oracle solution designed to handle secure message dispatching across chains. Spectre listens to dispatched messages from supported chains and verifies them on the destination chain using cryptographic proofs.
verifies the consensus of a source chain in the execution environment of a destination chain. For example, you can run an SP1 Helios light client on Gnosis Chain that verifies Ethereum Mainnet's consensus.
